Greater London: sliding patio doors

Sliding doors can have a raised sill for weather resistance or a low, flush track for near level access between floor and patio. Flush tracks need good drainage outside and some shelter, and on exposed elevations a slightly raised threshold usually keeps water out more reliably.

Keep sliding doors running smoothly by vacuuming the bottom track and drainage slots regularly, wiping the tracks with a damp cloth and checking the brush seals. Avoid oil on the track itself, which attracts grit. Rollers can be adjusted when a panel starts to drag or the lock no longer lines up.

Older patio doors with worn rollers often feel heavy and grind along the track. Modern sliding doors use adjustable stainless or sealed bearing rollers designed for heavy glass, but they still need a clean, level track. Grit in the bottom track is the main reason a sliding door becomes stiff.

In England, a replacement door with more than 60% of its internal face glazed should achieve a U-value of 1.4 W/m²K or a Doorset Energy Rating of band C under Approved Document L. Large sliding doors in new extensions are assessed within the extension's energy calculations.

What applies in Greater London

Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.

Replacing windows and doors with similar ones is usually permitted development for houses in England. Flats, listed buildings and homes in conservation areas or covered by an Article 4 direction can need permission, so check with the council first.

Parts of Greater London are within about 15 km of the coast, where exposure to wind and salt air is worth planning for. Salt and sand collect in sliding door tracks near the coast, wearing rollers and seals more quickly, so tracks need more frequent cleaning. Stainless running gear, a coating suited to marine exposure and a raised threshold help on exposed elevations facing the sea.

Large sliding panels are heavy and long, so city installations need planned access through the house, parking nearby and sometimes lifting equipment for upper floors or balconies. Flats need freeholder consent and planning permission, and acoustic glass helps on busy roads.

Sliding Doors in Greater London: questions

How much do sliding patio doors cost?

The cost of sliding patio doors depends on the width and height, the number of panels and tracks, aluminium or uPVC, standard or lift-and-slide hardware, colour, glass and threshold. Large slimline aluminium systems sit at the upper end. See the guide prices for typical ranges; the written quote fixes the price for your exact specification.

How long does it take to install sliding doors?

Replacing a typical set of sliding patio doors takes about a day on site, and large multi-panel or lift-and-slide systems can take longer, especially if lifting equipment is needed. The doors are made to order first, and the manufacturing lead time is confirmed in writing when you accept the quote.

Can I get sliding doors with a very slim frame?

Yes. Slimline aluminium sliding doors are designed with narrow outer frames and interlocks, and some systems hide part of the frame in the floor, walls or ceiling. Very slim systems need precise, level openings and strong support above, so the survey checks the lintel, floor and walls before recommending one.

What guarantee comes with sliding patio doors?

Manufacturer guarantees apply to the frames, coating, rollers, locks and sealed units, and the terms are confirmed in writing. Cover for rollers can depend on regular cleaning, so read the conditions. Guarantee terms for the installation are set out in writing with your quote, so you know exactly what is covered before you go ahead.
